FAA issues Emergency AD for some Rotax 912 engines

The FAA has issued an emergency airworthiness directive affecting certain Rotax 912 series engines. According to a report at EAA.org, the AD requires that the pressure side fuel hose be replaced on fuel pumps with the certain serial numbers. An AD from the European Aviation Safety Agency indicates that the pressure side fuel hose on these pumps may not be manufactured to full fuel-resistant standards, which could result in the degradation of the interior of the hose and the resulting debris fouling the fuel system.

These numbers refer to manual fuel pumps:

11-3117 through 11.3325 inclusive

11-4036 through 11-4355 inclusive

11-4516 through 11-4595 inclusive

12.0251 through 12-0270 inclusive

An AD from the European Aviation Safety Agency indicates that the pressure side fuel hoses on these pumps may not be manufactured to full fuel-resistant standards, which could result in the degradation of the interior of the hose and the resulting debris fouling the fuel system.

The AD becomes effective Monday, September 10. Affected owners have five flight hours from that date to make the prescribed repairs. EAA advises owners of Rotax 912-powered aircraft – type certification and non-type-certification – to check the AD to determine if your engine is among those affected.

    I have flown several of these aircraft. Everyone of them seemed to have a rigging problem. They just didn’t fly straight so you were constantly dancing with your feet. They just didn’t fly straight. Other than that, I thought it was nicely made. Just didn’t fly straight. I am not the only one who has said this. Has this issued been fixed?

      The Allegro has Text book adverse yaw. This is why we like it as a rudder trainer. That being said, the last batch of planes that came from over seas did have an issue with the horizontal stabilizer angle. This has been corrected which increased both speed and stability. Other stability problems tend to be more caused by over control, improper pilot input and a lack if a true understanding of adverse yaw. This is why I find this aircraft the perfect primary trainer.

  2. Somebody necessarily lend a hand to make seriously posts I would state. That is the very first time I frequented your website page and so far? I amazed with the analysis you made to create this actual publish extraordinary. Excellent activity!
